CyberRota Analysis

AI-Generated

The vulnerability in 9Router allows remote unauthenticated attackers to bypass API key protections for the /codex endpoint, enabling unauthorized access to upstream provider calls using sensitive operator-stored credentials. This poses a significant risk of data exposure and potential misuse of AI resources. Organizations utilizing versions prior to 0.5.2 should prioritize updating to mitigate this high-severity security flaw.

Original NVD Description

9Router is an AI router & token saver. Prior to 0.5.2, 9router protects /v1, /v1beta, /api/v1, and /api/v1beta in src/dashboardGuard.js but omits /codex before next.config.mjs rewrites /codex/* to /api/v1/responses. A remote unauthenticated attacker can send requests to /codex/* to bypass the API-key gate and cause the server to make upstream provider calls using operator-stored LLM provider credentials. This issue is fixed in version 0.5.2.
